摘要: Abstract Single crystals of C.I. Disperse Red 65 and 73 were grown from ethyl acetate acetonitrile/toluene solutions, respectively, their crystal structures determined using single-crystal X-ray diffraction analysis. In each dye molecule, the aminoazobenzene framework is almost planar due to intramolecular H-bonding. case 65, intermolecular associations occur by π–π stacking H-bonding, resulting in a herringbone-type arrangement; for 73, toluene molecules stabilize structure via stacking.
